Buy Master Call Point – Wireless Lockdown Alarm Trigger for Schools, Venues and Workplaces
This Master Call Point is the main trigger for your wireless lockdown alarm system. A single press sends a secure
signal to all linked lockdown sounder and beacon units, helping staff warn pupils, visitors and team members within
seconds – without relying on Wi-Fi, internet or complex cabling.

Overview
If you need a clear and simple way to trigger a lockdown across your site, this wireless Master Call Point does exactly that.
It is designed for schools, academies, theatres, nurseries, offices, warehouses, hotels and other UK venues that want a reliable,
easy-to-use lockdown trigger as part of a wider lockdown alarm system.
The unit acts as the “heart” of your lockdown setup. It is usually positioned in a key location – such as reception,
a school office or a security control point – and when pressed, it tells every paired lockdown sounder and beacon unit to activate.
Once the situation is under control, you reset it using the supplied key so it is ready for the next drill or real event.
Key Features of the Master Call Point
- Main activation point for your wireless lockdown alarm system.
- Single press sends a site-wide lockdown alert to all paired units.
- Uses its own secure wireless signal – not reliant on Wi-Fi, 4G or your IT network.
- Battery powered, so it continues working during power cuts.
- Ideal for UK schools and busy workplaces improving lockdown and emergency procedures.
- Works as part of small starter systems or larger multi-building layouts.
- Manual key reset so alerts can be safely cleared after activation.
How the Master Call Point Works
The idea is straightforward: you position a clear, visible lockdown button where trained staff can access it quickly,
then let the wireless system handle the rest in the background.
- A member of staff presses the Master Call Point during a lockdown or critical incident.
- The unit sends a secure wireless signal across the site.
- All internal and external sounder and beacon units activate together.
- Pupils, staff and visitors recognise the lockdown alarm and follow your procedures.
- Once the situation is over, the system is reset using the supplied key.
Because everything is wireless, there is no need to disrupt your building with new cabling. This makes it particularly useful for
older school buildings, listed sites and busy environments where rewiring would be expensive or difficult.
Where This Master Call Point Is Typically Used
The Master Call Point is most commonly installed in education and public environments, but it suits a wide range of settings:
- Primary and secondary schools needing a dedicated, easy-to-reach lockdown trigger.
- Multi-academy trusts and colleges with multiple buildings on one campus.
- Theatres and performance venues where discreet, wireless alarm solutions are needed.
- Nurseries and childcare settings where simple activation and clear alerts are essential.
- Offices and commercial buildings strengthening security and incident response procedures.
- Warehouses, factories and industrial sites requiring clear audible and visual alerts.
- Hotels, conference centres and public venues with high visitor footfall.
Many of these environments are now reviewing their arrangements in light of Martyn’s Law (Protect Duty),
and the Master Call Point forms a simple, easy-to-understand part of that wider response plan.
